    Which term is defined as the "measure of how packed the atoms of a substance are"?

    • Cutaneous

    • Footcandle

    • Density

    • Blowing Sand

    Correct Answer
    A. Density
    Explanation
    Density is the measure of how packed the atoms of a substance are. It is defined as the mass of a substance divided by its volume. In other words, it tells us how much mass is contained within a given volume. A substance with a high density has its atoms tightly packed together, while a substance with a low density has its atoms spread out. Density is an important property in various scientific fields, such as physics, chemistry, and materials science, as it helps in understanding the behavior and characteristics of different substances.

    Which of these is formed after a supernova explodes and shrinks?

    • Carnivore

    • Paleontologist

    • Neutron Star

    • Tide

    Correct Answer
    A. Neutron Star
    Explanation
    A neutron star is formed after a supernova explosion and shrinking. When a massive star reaches the end of its life, it undergoes a supernova explosion, releasing a tremendous amount of energy. This explosion causes the outer layers of the star to be blown away, leaving behind a dense core. The core collapses under its own gravity, causing protons and electrons to combine and form neutrons. The result is an extremely dense and compact object known as a neutron star. These stars have a mass greater than that of the Sun but are only about 20 kilometers in diameter.
